It is publicly announced that concentration of formaldehyde in the air is at average 2.4 μg/m3 and maximum 5.3μg/m3 at the 306 points in Japan by Ministry of environment. Based on this result, the crisis rate of carcinogen is at the average 26 and the maximum 58 per 100,000 person if a man spend outside from 0 years old to 70 years old.
Guideline of formaldehyde concentration by Ministry of health, labor and welfare in room is "100μg/m3: 0.08ppm". This guideline is for sick house syndrome but not for carcinogen. The crisis rate of carcinogen in room is very high rate as maximum 1 per 100 persons under exposure with guideline (by unit risk of EPA if a man spend inside of room from 0 years to 70 years old.)
To reduce formaldehyde concentration in room as less as possible decreases crisis rate of carcinogen and helps to live healthy. In addition, it is effective to low immune children, it contributes to prevent decreasing population. It fulfills educational institute and corporate social responsibility.

Unit risk : upper limit of expected crisis rate of carciongen under exposure every day from 0 to 70 years old.
Risk of carcinogen : the figure based on calculation of 1 person out of 11000 will be cancer because of formaldehyde at 1μg/m3
Risk of carcinogen : the figure based on calculation of 1 person out of 11000 will be cancer because of formaldehyde at 1μg/m3
guideline & reguLation for carcinogen formaldehyde
unit risk : Crisis rate of carcinogen
to calculate crisis rate of carcinogen assuming risk for infants less than 2 years old is 10 times more and risk of young people less than 16 years old is 3 times more in case of 70 years of lifetime.
Ministry of economy, trade and industries and ministry of environment have been specified as class I specified chemical substances (carcinogen)
Emmision of carcinogen in domestic residence is only formaldehyde.
Total 15 chemical substances.
Total 15 chemical substances.
comparison between Risk of death from carcinogenesis by radiation exposure and risk of carcinogenesis by exposure under formaldehyde guideline
Annual average radiation exposure for Japanese is 1.4 mSV.
Lifetime (70 years) radiation exposure is 98 mSV.
The number of deaths by carcinogenesis is 0.122 out of 100 persons.
The number of carcinogenesis by exposure under formaldehyde guideline is maximum 1 out of 100 persons.
Lifetime (70 years) radiation exposure is 98 mSV.
The number of deaths by carcinogenesis is 0.122 out of 100 persons.
The number of carcinogenesis by exposure under formaldehyde guideline is maximum 1 out of 100 persons.
